Frequent visitors to ForPrin.com may have noticed that the Forecasting Methodology Tree and the Forecasting Method Selection Tree have changed. Earlier this year, we replaced the Trees with versions that better represent the current state of forecasting knowledge. Since then, we have been fixing and revising the pop-up windows so that they are consistent with the new Trees. The Trees remain a work in progress--we will continue to improve the pop-up descriptions and add relevant links--so please let us know if you spot any problems or have any suggestions for improvements. See the links to the new Trees in the menu bar at the top of the screen.

Alain Elkann interviews famous people, iconic people. The three listed in his interview directory under the letter B, for example, are Ban Ki-Moon, Bianca Jagger, and Brigitte Bardot. During his current visit to the University of Pennsylvania, Alain recently interviewed co-founder of the International Institute of Forecasters, International Journal of Forecasting, and International Symposium of Forecasting, J. Scott Armstrong.

Curious about what led Scott to so many contrarian conclusions, Alain interviewed him about his life as a scientific skeptic. Naturally, the interview revolved around Scott's forecasting research. As a consequence of the interview, the discipline of forecasting is now aligned with the stars. The interview is currently the Most Read.

The Lancaster Centre for Forecasting is running a survey to gain insights into what drives the improvement of forecast quality in practice. Click here to take the survey.

The research is not for commercial purposes and all responses are strictly confidential. That means there will be no results reported/discussed/etc. at an individual company or respondent level. The survey will take about 5 minutes depending on how much information-sharing you provide.
